Like a clock ticking away your profits, every extra minute in the kitchen adds real costs to your delivery dishes. That beef wellington might taste amazing, but those 45 minutes of prep time can silently drain your margins. Here's how to calculate what those time-consuming dishes actually cost you.
Why production time affects cost price
Delivery orders seem straightforward - ingredients plus packaging, right? But that slow-braised short rib tying up your chef for an hour costs serious money in wages, utilities, and kitchen capacity that could handle three quick dishes instead.
💡 Example:
Your standard pasta takes 8 minutes. A beef tenderloin needs 40 minutes (5x longer):
- Pasta: 8 minutes × €25/hour chef = €3.33 labor
- Beef tenderloin: 40 minutes × €25/hour chef = €16.67 labor
Difference: €13.34 extra labor costs per portion
The 4 components of a time-consuming delivery cost price
Your true cost price includes four distinct elements:
- Ingredient costs: every component that goes into the dish
- Labor costs: chef time × hourly wage
- Energy costs: additional gas/electricity from extended cooking time
- Packaging costs: containers, bags, labels for delivery
⚠️ Watch out:
Most ghost kitchens focus only on ingredients and ignore labor costs. With time-intensive dishes, this oversight can destroy 30-50% of your margin.
Calculate labor costs per dish
The math is straightforward:
Labor costs = (Prep time in minutes ÷ 60) × Chef hourly wage
💡 Example calculation:
Slow-cooked pulled pork for delivery:
- Prep time: 45 minutes active work
- Chef hourly wage: €24.00 (including employer contributions)
- Labor costs: (45÷60) × €24 = €18.00
Add ingredients (€8.50) and packaging (€1.20) = €27.70 total cost price
Include energy costs in the calculation
Extended cooking times mean higher utility bills. Use these benchmarks from tracking this across dozens of restaurants:
- Oven: €0.15 per hour
- Stovetop: €0.08 per hour per burner
- Deep fryer: €0.20 per hour
A dish taking 5x longer means 5x the energy costs.
Packaging costs for delivery
Delivery orders always require packaging that dine-in service doesn't need:
- Main container: €0.35-0.60
- Sauce cups: €0.15-0.25
- Delivery bags: €0.20-0.35
- Labels/stickers: €0.05-0.10
💡 Realistic example:
Beef Wellington for delivery (60 minutes prep):
- Ingredients: €12.50
- Labor: (60÷60) × €24 = €24.00
- Energy: €0.15 (oven 1 hour)
- Packaging: €0.85
Total cost price: €37.50
Include platform fees in your calculation
Delivery platforms charge 15-30% commission. Factor this into your minimum pricing:
Minimum selling price = Cost price ÷ (1 - Platform fee %)
⚠️ Watch out:
Platform fees aren't part of cost price, but they determine your minimum selling price. Always factor this into pricing decisions.
Making time-consuming dishes profitable
A dish requiring 5x longer prep can still work if:
- You can command premium pricing (luxury positioning)
- You batch-cook multiple portions simultaneously
- You prep during slow periods
- Cheap ingredients offset high labor costs
Tools like food cost calculators help you automatically track all these cost components and determine whether time-intensive dishes make financial sense for delivery.
How do you calculate the cost price of a time-consuming delivery dish?
Calculate all ingredient costs
Add up all ingredients that go into the dish, including spices, oil and garnish. Calculate with the exact quantities per portion.
Calculate labor costs
Measure the active preparation time and multiply by your chef's hourly wage. Formula: (minutes / 60) × hourly wage = labor costs per portion.
Add energy and packaging costs
Add the cost of gas/electricity (approximately €0.15/hour for oven) plus all delivery packaging such as containers, bags and stickers.
Calculate your minimum selling price
Divide your total cost price by (1 - platform fee %) to find your break-even price. At 25% commission: cost price / 0.75 = minimum price.
✨ Pro tip
Batch-cook time-intensive dishes in groups of 8-12 portions during your slowest 2-hour window each day. This cuts per-portion labor costs by 60-70% while maintaining quality.

Frequently asked questions
Should I include waiting time in labor costs?
No, only active preparation time counts. If your chef can handle other tasks while something simmers, you only calculate the hands-on time for this specific dish.
How do I calculate labor costs if I cook myself?
Use what you'd pay a chef (€20-25/hour). Even as the owner, you must value your time properly or you won't know if the dish is actually profitable.
Can I make time-consuming dishes cheaper?
Yes, through batch cooking. Making 10 portions simultaneously doesn't take 10x as long. You can also prep components during quiet periods to spread labor costs.
What if my cost price exceeds what customers will pay?
You have three options: modify the dish for faster prep, reduce portion sizes, or remove it from the menu. Operating at a loss never makes sense.
Does the calculation differ per delivery platform?
Cost price stays constant, but your minimum selling price varies because platforms charge different commission rates (15-30%).
How do I handle dishes with both active and passive cooking time?
Only count active time where your chef can't do other tasks. A 2-hour braise with 15 minutes of actual prep work costs €6.25 in labor, not €50.
Should I factor in kitchen rent when calculating time-consuming dishes?
Kitchen space costs are typically fixed monthly expenses. However, if a dish monopolizes equipment for hours, consider the opportunity cost of other orders you can't fulfill.
